(Cl. 1,2,6--'1)v 2 Claims.

This invention relates. to stoves and is particularly directed to. stoves having cooking and warming compartments which are so arranged as to enable waste cooking heat to maintain a high temperature in the warming compartment.

Objects of the invention comprise the provision of an efiicient stove adapted for deep fat frying or other cooking wherein the heated air arising from the cooking food is exhausted by suction means to pass directlybeneath a warming compartment, and wherein the exhaust gases from the fuel are separated from said heated air, but are withdrawn from the stove by the same suction means; the provision of a stove having a food warming compartment provided with a grease drain leading back to the cooking Dans, the latter having sliding closure means to prevent burning of the operator by spattering grease; the provision of a stove bottom element arranged to blow out upon a back-fire of the fuel, thus preventing injury to the cooking Dans and other parts of the stove; and the provision of novel arrangement of frying pans, closures, and warming compartments, all of which are easily removable from the stove base for cleaning or repair.

Other objects and advantages will appear hereinafter.

Reference is to be had to the accompanying drawings, in which Fig. 1 is a broken away front elevation of a stove embodying the present invention;

Fig. 2 is a section on line 22 of Fig. 1;

Fig. 3 is a top plan view taken in the direction of arrow 3 in Fig. 1;

Fig. 4 is an enlarged section on line 44 of Fig. 3;

Fig. 5 is an enlarged section on line 55 of Fig- Fig. 6 is a perspective view of a drip pan; and

Fig. 7 is a perspective view of a drain grille.

The stove illustrated may be made as a single cookin and warming unit, or it may be manufactured in a plurality of such units on a single base. Figs. 1 and 3 show a complete unit and part of another, to indicate this construction, and it is to be noted that a single unitary frame having legs Ill is provided, these legs being connected by sheet metal sides l2, front wall I4, and

rear wall 16. An angle iron or other support l8 is secured to the top of the rear wall, and an inturned bottom flange 20 cooperates with a flange 22 at the bottom of front wall M to support an apertured false bottom 24 by small Z-shaped metal clips 26.

The front Wall I4 comprises a pair of sheet metal elements 28 separated by a layer of asbestos3il, the outer elementbeing bent over top. and bottom flanges of the inner element and crimped thereto to provide a strong rigid structure and the supporting flanges 22 and 32. The angle iron l8 extends the width of the stove and has secured thereto one end of an inverted channel element 3.4, the other end of which is secured to the front wall M in any desired or convenient manner. It is to be understood that a plurality of elements 34 will be used for a like number of cooking units and that the end supports as at 36 may be or like construction, if desired, although this is not necessary as the side walls l2 may be flanged corresponding to flange 32.

The cooking vessels or pans 38 are of novel construction and are formed with side and end flanges 40 which fit over angle iron l8, front flange 32, and channels 34, the pans depending from these flanges as shown. Each pan has a rear wall 42 spaced from the stove wall I 5 and an inclined grease apron 44, so that any grease falling on the apron will be returned to the pan.

A unitary sheet metal apron comprising a front element 46 having a depressed guideway 48, an end element of similar nature 50, and channel cross-pieces 52, is provided to fit down over the pan flanges as they rest on their supports, thus holding them in place and providing a finished appearance to the stove. The cross-piece 52 is shown in section in Fig. 5, wherein it will be seen that it comprises an inverted U-shaped channel having outstanding flanges 54. Flanged sliding doors 5B are supported on and guided by these flanges, there being a stop 58 to prevent complete rearward movement of the doors. A gas pipe 60 runs along the front of the stove and ha transverse burners 62 located just under the pans, valve operators 64, and a cover plate 66. Front wall l4 may be provided with doors 68 for access to the burners, and the enlarged compartment to the rear of the burners may be provided with an exhaust opening having a conventional valve 10, the opening leading to a pipe 12.

The warming compartment 14 comprises a unit entirely separate and removable from the cooking structure, resting on apron 46, 50, and being attached thereto by clips 16. The warming unit has a continuousrear wall 18 interrupted only by an opening communicating with a pipe leading to pipe 12. The compartment bottom is entirely open and forms a single air chamber with the pan 38 as shown in Fig. 2. There is a front wall 82 resting on cross-piece 52, the front wall being shorter than the-rear wall. A removable drip plate 84 rests on supports 86 and has a downspout 88- located horizontally to the rear of stop 58. Side flanges 98 locate the drip pan and a flanged grille 92 is set into the drip pan to drain cooked food. A pivoted door 94 is used to close the food compartment, and an appropriate stop 98 is provided therefor.

Sliding door 56 is the same width as the warming compartment and has a rear lip 98 which engages the lower edge of wall 82 to prevent complete closing of the pans, thus providing an air entrance space I80 while the cooking is in progress.

In the operation of the device, heat is obtained from the gas burners to cook food of any kind which may be placed in wire baskets within the pans. Doors 56 will prevent spattering of the grease while openings I provide for admission of air over the grease in the pans. This air becomes hot'and mixed with smoke and fumes, and is exhausted into pipe 88 directly under the warming compartment. When doors 52 are open, stops 58 will prevent complete cutting ofi of the air flow, so that the latteris continuous at all times, and also the opening of a door cannot interfere with the return of the grease down thru outlet 88 onto inclined element 44. This construction provides for a positive heat to keep the food-warming compartment effective, and also draws off all cooking-odors and smoke.

The gas fumes are also drawn oif thru pipe 12, the valve I0 being useful to control the draft, and it Will be seen that the gas chamber, cooking chamber, and warming compartments are all separated, and no contamination by waste gas,

smoke, or odor is possible.

The pans 38 are firmly held in position by the apron element 46, 58, 52, which provides guides and support for'doors 56, and which is held down on the fram I 4, l6. at least in part, by th weight of the warming compartment, and guideway 48 may be used for slidably receiving food holders. The pans are easily removed by taking off clips 18, lifting the warming compartment oiT the apron 46, and in turn lifting the latter off the pan flanges 48, and the advantages of the present construction, which provides a rigid assembly which can be easily disassembled, will be apparent.

In case of a back-fire in the gas chamber, the clips 26 will be bent in a manner to let the bottom 24 fall or blow downwards, thus preventing injury to the pans by blowing them upwards against the apron 46 and the warming compartment.

Having described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:

1. A stove comprising an open top cooking vessel having a rear wall, a drip apron extending upwardly and rearwardly from said wall, a heating compartment below said vessel, a warming compartment associated with said vessel and located to the rear thereof and generally above said drip apron, said warming compartment having an open bottom, a front wall in part defining said bottom, said front wall being approximately vertically above said vessel rear wall so that gases from the vessel are enabled to rise up said apron into said warming compartment, the latter being enclosed except for its open bottom, a gas exhaust at the rear of the stove for said Warming compartment, a horizontally slidable door for said vessel forwardly of said warming compartment, and means preventing complete closing of said vessel by said door, whereby an air entry and cooking gas exit are alway maintained for said vessel.

2. A stove as recited in claim 1 wherein said door is slidable rearwardly to vessel-open position substantially within said warming compartment and forwardly to substantially vessel-closed position, there being a stop on said door engageable with said front wall to provide said complete closing preventing means, whereby said air entry is located at the front of the vessel.
